Big Grid Issues

Revit is great because you don't have to repeatedly draft things like grid lines. Put 'em in once and you're good to go. That is, until you have to show a keyplan with grids or you have a project so large you have to show it at something like 1/32" scale or 1"=50'-0". Now the grid bubbles appear to be 20' diameter. Because the grid text and bubble maintains the same size regardless of scale, it doesn't work well when you combine large and small scales.

Thankfully, there's a workaround. This one is courtesy of the Revit OpEd blog (see Knowledge Base links on your right and link below).

A solution to show different size grid annotation in large scale views involves using Design Options.

1. Create a Design Option called Grid Management and two options: Normal Size and Reduced Size.
2. Create a Reduced Size Grid type that uses a grid bubble family with smaller text and circle. Rename the normal Grid type: Normal Size.
3. Add all the Normal Size grids to the project and then add them to both Design Options.
4. Edit the Reduced Size view's Design Option and change the grid types to the matching Reduced Size grid type. In the larger scale views set their Design Option (via Visibility/Graphics dialog) to display the Reduced Size Design Option.

Now you have smaller grid bubbles and they "look" better...just keep in mind that they are smaller and now harder to read when printed full size, or half size for that matter.

Caution: Dimensioning to these grids in a design option and to the rest of the model can have unpleasant issues. Such as the dimension getting deleted or at least disappearing when the relationship between the Option"ed" grids are no longer relevant. This can happen if you toggle the assigned option to another and back.
